1.4 RELEASE INFORMATION
On July 27, 2022, during annual UST system testing, the premium gasoline product line was found to fail its
tightness test. The premium UST system was taken out of service at that time. Circle K contracted with a
subcontractor to determine the cause of the premium gasoline line failure. It was determined that there was an
issue with the product line flex connector that was connected to the premium gasoline submersible turbine
pump (STP). Subsequently, the flex connector was repaired, and a containment sump was installed at the
Initial Abatement Action Report ATC Associates of North Carolina, P.C.

premium gasoline STP sump. The containment sump was hydrostatically tested on February 9, 2023 and the
premium gasoline product line was tested on February 16, 2023. The premium gasoline product line passed its
tightness test on this date. The premium gasoline UST system was placed back into service. Copies of the
referenced testing results are provided in Appendix A.

A previous release has been documented at the facility. The release was issued UST incident number 32249.
This incident was issued a Notice of No Further Action after the recordation of a Notice of Residual Petroleum
(NORP). Monitoring wells had been installed as part of assessment activities for UST incident number 32249.
It was determined that the monitoring wells had never been abandoned; therefore, the existing monitoring wells
(MW-1, MW-2, and MW-3) were utilized for activities documented in this report.

Upon receipt of the groundwater analytical results, a 24-Hour Release and UST Leak Reporting Form was
submitted to the NCDEQ. A copy of the release notice is provided in Appendix B.

contour map is provided as Figure 3. Groundwater appears to flow toward the southwest.
6.0 GROUNDWATER SAMPLING AND RESULTS
On April 17, 2023, groundwater samples were collected from monitoring wells MW-1, MW-2, and MW-3. The
monitoring wells were purged prior to sampling by removing a minimum of three well volumes of water from
each well. After allowing sufficient time for recharge, a representative groundwater sample was collected from
each well using a new, disposable Teflon bailer. Upon collection, the groundwater sample was placed into
laboratory-approved containers, packed in ice, and delivered under chain-of-custody to SGS North America
(SGS) in Scott, Louisiana for analyses. The groundwater sample was analyzed by Environmental Protection
Agency (EPA) Method 6200B to include ethanol and oxygenates, EPA Method 6020 for lead, EPA Method
504.1 for ethylene dibromide (EDB), and Massachusetts Department of Environmental Protection (MADEP)
method for volatile petroleum hydrocarbons (VPH).

Laboratory analytical results of the groundwater samples collected from monitoring wells MW-1, MW-2, and
MW-3 detected several dissolved target compound concentrations above established 2L Standards. It should be
noted the dissolved benzene concentration in the groundwater sample collected from monitoring well MW-2
was detected above its established Gross Contaminant Level (GCL). A summary of the groundwater analytical
data is presented in Table 2. Dissolved contaminants of concern are depicted on Figure 4. A copy of the
laboratory analytical report is included as Appendix C.
7.0 CONCLUSIONS AND RECOMMENDATIONS
7.1 CONCLUSIONS
Based on the information obtained during initial abatement action activities, the following conclusions are
made:

• The premium gasoline product line failed its annual tightness test. Repairs have been made and
the premium gasoline line was retested and found to pass its tightness test. The premium
gasoline UST system has been placed back into operation.

• The subject property and surrounding properties appear connected to the public water system.

• Surface water bodies were not identified within 1,500 feet of the source area.

• The source area is not located in an approved wellhead protection area.

• Laboratory results of the groundwater samples collected from monitoring wells MW-1, MW-2,
and MW-3 detected several dissolved target compound concentrations above established 2L
Standards. The dissolved benzene concentration detected in the groundwater sample collected
from monitoring well MW-2 was found to be in excess of the established GCL.
7.2 RECOMMENDATIONS
• A copy of this report should be submitted to NCDEQ.

Annual Shear Valve Testing : 2022
Shear Valve Test Criteria
>This data sheet is for inspecting shear valves located inside dispensers. See PEI/RP 1200, Section 10 for the inspection procedure.
>This form may be utilized to document testing of shear valves (a.k.a. impact, crash, safety or fire valves).
>Testing of all shear valves is required at least once every 12 months.
>In the absence of an approved 3rd party test procedure or manufacturer's recommended practice, the procedure outlined below in the "Shear Valve Test
Procedure" section may be utilized.
Shear Valve Test Procedure
1.Visually confirm that all shear valves are properly installed, "trip" mechanism is functional and in good condition.
2.Manually close the shear valve.
3.Energize the pump and attempt to dispense fuel from the corresponding nozzle into a suitable container.
4.Confirm that the shear valve effectively interrupts the flow of fuel so that no fuel is dispensed from the nozzle.
5.Return the nozzle to the hanging position and shut down the pump.
6.Return the shear valve to the open position ensuring "trip" mechanism is functional and in correct position.
NOTE: State certification as a UST installer is required to repair or install shear valves

Definitions of Sources Tank: means the tank that stores the product and is part of the underground storage tank system Piping: means the piping and connectors running from the tank or submersible turbine pump to the dispenser or other end-use equipment (Vent, vapor recovery, or fill lines are excluded.) Dispenser: includes the dispenser and the equipment used to connect the dispenser to the piping (e.g., a release from a suction pump or from components located above the shear valve) Submersible Turbine Pump (STP) Area includes the submersible turbine pump head (typically located in the tank sump), the line leak detector, and the piping that connects the submersible turbine pump to the tank Delivery Problem: identifies releases that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfills.)
Other: serves as the option to use when the release source is known but does not fit into one of the preceding categories (e.g., for releases from vent lines, vapor recovery lines, and fill lines) Unknown: identifies releases for which the source has not been determined Definitions of Causes
Spill: use this cause when a spill occurs (e.g., when the delivery hose is disconnected from the tank fill pipe or when the nozzle is removed from the dispenser) Overfill: use when an overfill occurs (e.g., overfills may occur from the fill pipe at the tank or when the nozzle fails to shut off at the dispenser) Physical or Mechanical Damage: use for all types of physical or mechanical damage, except corrosion (e.g., puncture of tank or piping, loose fittings, broken components, and components that have changed dimension) Corrosion: use when a metal tank, piping, or other component has a release due to corrosion (e.g., for steel, corrosion takes the form of rust) Installation Problem: use when the problem is determined to have occurred specifically because the UST system was not installed properly Other: use this option when the cause is known but does not fit into one of the preceding categories (e.g., putting regulated substances into monitoring wells) Unknown: use when the cause has not been determined
